INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented May 7, 1918.

Application filed April 6, 1916. Serial No. 89,293.

To all whom, it may concern.

Be it known that I, Amuurr llunuann, a citizen of the United States of America, residing at the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in lnternal(.onr bustion Engines, of which the following is a specification.

My invention relates to internal combnstion engines, and particularly to that type of such engines in which liquid fuel is used to operate the same, and furthermore \vith which a; pump pumps, or other similar means are employed to inject the fuel in predetermined quantities into the cyl triers of the engine at predetermined times of ring the compression strokes of the pistons.

As is generally recognized, liquid i'l iels are of many different grades, and in order to obtain complete combustion ant conscquent economy in the operatic n of liquid fuel engines, it is necessary to inject some grades of fuel at one time and other grades at another time, certain oils requiring earlier and certain other oils requiring later injection during the compression stroke.

Now the object of my invention is the pro vision of a liquid fuel engine, with associated parts so constructed that. the time of injectmg the fuel may be ad usted and so regulated and controlled during the running of the engine, depending of course upon the This result is accomplished by the apparatus constructed in accordance with my invention, and in which, as will hereinafter appear. I dispense entirely with the use of auxiliary or counter-shafts and the necessary accompanying gear or chain transmission, in o wanting the pump, or pumps, em 'il'oyer to oretfthe oil into the cylinders, by which construction, as power utilized in operating the pumps to inject; the fuel is n'iaterially reduced. Flll'tllfllllfllfi, the construction of the injection time controlling devices is such that the same may beso operated as to obtain the necessary pro-ignition to reverse the engine.

In carrying out my invention, the parts are also so constructed and associated as to act in conjunction with a suitable governor apparatus, which, depndingupon the speed of the engine, controls the quantity of fuel forced into the cylinders at each injection. Still furthermore=- in order to prevent over heating of the cylinders and the igniters, I

' plungers.

provide for the injection. of a predetermined quantity of water with each injection of the oil or other liquid fuel, so adjustment of theu'ater supply, the governor will so control the injection of the oil and water as to maintain the cylinders and igniters at a substantially constant temperature, even under varying or excessive loads.

It is also a part of my present invention to provide suitable means for controllin the stroke of the pump pistons indepen ently of the governor and the injection time controlling devices, so that both may be em- 'iloyed in conjunction with one another in reversing or in stopping the engine.

The improvements comprising this invention will he hereinafter more particularly described in conjunrtion with the accompanying drawing. in which Figure 1 is an elevation illustrating a tu'o-cylimler engi with which the apparatus comprising in... invention is employed.

By reference tethe drawing, it will be seen that in Fig. 1, I have illustrated more or less diagrammatically a two-cylinder en glue in which my present invention is embodied,-althou h, will be understood, this invention mayfiie employed in engines of any number of cylinders.

In the drawing 10 indicates a base plate which may be supported upon any suitable foundation. Connected to the base plate are the cylinder bases 11 and 12, supporting the cylinders 13 and 14 respectively through the intermediate rod and crank cases 15 and 16. T

The engine shaft is indicated at 17, and as usual may be provided with a fiy wheel 18.

The cylinder base 11 and the crank and rod cases 15 are suitably fitted with brackets or side extensions 19 and 20, respectively, and to the'extensionltla frame member 21 is secured by means of bolts 22, or other- W188, the upper portion of this frame membar abu in sion 200 t e rod and crank case 15.

,By reference to Figs. 3, 4, and .5, it will .be seen that the frame member 21 is provided' centrally with an opening 23, and in the face adjacent the brackets 19 and 20 with a recess indicated at 24;

Suitably connected to this frame member 21 there are also provided brackets 25 and 26. These brackets atructed. In the bracket 25 there is a pump jplunger bearing 27, and in the bracket 26 51a. similar bearing-28. Also in the bracket.

are similarly con- 'strap, t

31 and the bracket 26 with similar bolt holes 32. In the inner portion of the bracket 25 the same is centrally slotted, as indicated at 33, and similarly on the inner portion of the bracket 20 the same is slotted, as indicated at 3- In Fig. (i, as illustrated, the auxiliary frame is employed in connect on with the frame member 2.1, the same being designated by 35. This auiiiliary frame member 35 is provided with brackets 36 and 37 adapted to rest upon and be secured to the brackets H) and 25, respectively, on the frame mom i 21. lhe bracket J-lli is provided with a 81 3' bearing 38. which, with the shaft beari 250 completes the hearing for a shaft in be ln'rcinnftmdescribed. Similarly the bracket 37 is provided with a shall bearing; ll which. with the shaft bearing, 2 forms a hearing for a shaft to be hereinafter des ribed.

'lhc auailiar frame 35 is secured in position to the frame member 21 by the bolls 40 and 41, which pass through the bolt holes ill and 32, respectively, in the frame member 21 and into the bra kets 35? and 3H on the auxiliary frame 15.

()n the upper portion of the auxiliary frame member 35 there are lugs l2 and lil, the purpose of which will hereinafter appear.

In Figs. 7 and 8. 1 have illustrated a disk 44 having a central opening 45 therein and on one face rovidcd with a flange ll} with an opening of the same diameter as the opcn illg lfi. The flange ill, when the parts are assembled, passes through the opening 2? in the frame member '31. and this nn-mber is revolubly secured in position in the frame member 21 by a tie plate 47 whit h is secured to the flange 46 by means of the screws 48. or otherwise.

Secured in the face of the disk 44, there are guide plates 49 and 5f), the former bring fixed in position by bolts 5i and the latter by ,bolts 52, or otherwise. As'rlcnrlv shown inul ig. 8, these platcs together with lhe body portion of. tl'l( (ll$l{, provide guidw contact surfaces for actuating the pump.

plungers, aslwill be hereinafter more par ticularly described.

The bracket 56, at one end of the reciproeating plunger )late 55, is provided with a bearing 58 in w ich there are bolt holes 59.

In FIE. 11,,there is illustrated an eccentric 60 and 61. These parts, on opposite sides,

Ill!) parts of which are indicated at portion 11; fitting over the spring-11h and The pump body is provided with a flange 110.. by which it is suitably connected to the t'rame member 21. a nimp h'eing provided as indicated in Fig. 2 ineach end of this frame memher.

Each pump also includes a plunger 111 passing through the flange 110 into the pump chamber 104, and operating in a sleeve 112 extending from the pump body and flange. h

At its outer extremity. the plunger 111 is flanged. as indicated at 113, and this end of the plunger is adapted to contact with. a hoe 114. provided for this purpose on an auxiliary plunger 11?, and to he maintained in this position by a spring 114'. which sur rounds the sleeve 11;! and extends between the inner face of the flange lit) and the nth jacent face, of the flange 113.

The auxiliary plunger 11? has a socket.

terminating sullieiently far from the flange IN) to permit the auxiliary plunger to he moved, so as to move the main plunger to operate the pump. The socket portion 117 of the auxiliary plunger slides in a .plunger hearing 27 on the frame 21.

As indicated in Fig. 17. the auxiliary plunger 11!) at its inner end is recessed at HS and the. inner end 11!) of the auxiliary plunger is the contact. surface against which one end of the reeiprm-atiug contact plunger .17 strikes in the o a-ratiouof the apparatus,

hereimil'ter described, to actuate the plunger and so o 'ierate the pump.

As hereinhetore intimated, my invention j also comprises suitablc means for limiting 'eoni'prise slop levers 1:20 and 121.

the position ot' tlhe plunger and auxiliary plunger of each pump. and consequently" determining the length of its stroke. 'l'hese parts are shown in Fig. 2, and illustrated more particularly in ,l igs. 11) and 20. 'l'he These are adapted to pass through the recesses 33 aml'li-l in liraekets 2:) and 2t. oi the frame me'nher 11. and into the" recessed inner ends of the auxiliary plungers of the whip. these parts being clearly shown in t \is position in Fig. 2.. V

The stoplever 120 is connected to a shaft 122; and the stop lever 1'21 to a shaft 123.

The Shaft 122. journaled in bearings 29 and 39, in tllfibftflfllitttt-{Qfi andffl't and similarly the shaft" 123 is ujoulinaled in the bcarposite that engaged in the recess 118 in t end of the levers shownat 145 and 146.

Tlholever 145 is connected to a shaft 147 j the shaft 130, which 'is also journalpd in the auxiliary frame 35, and connected to the shaft 130 is a lever 131.

Also on the shaft 127 and on the opposite side of the eccentric 126, the same s provided with a segmental gear 132. This segmental gear 132 meshes with a simila segmental gear 133 mounted on a shaft 13 also journaled in theauxiliary frame 35.

Also on the shaft 134 there is an eccentric 135 similar to; the eccentric 126 but oppo' sitely placed. An eccentric stra 136 i fitted around the eccentric 135, an this eccentriestra p 136 is atone end of a rod 137, the opposite end of which is pivotally connected to the end of the stop lever 1210p 115 inner end of the auxiliarylplunger of the pump on the opposite side of the frame member 21.

At its frte end the lever 131 is provided with a handle 138 and a spring actuated trip member 12-59 and tongue 140. the latter being adapted to engage the teeth 141 in the. ed 0 of the segmental bar 142, which alsoextent s hetween and is suitably connected to the lugs 42, extending, upwardly from the upper portion of the auxiliary frame 35.

It will be apparent that by the operation of the lever 131, the shaft 130 21nd segmental gears, stra s, and eccentrics "actuated thereby may e operated to corres ondingly move the stop levers 120 ant 121 through the rods 134 and 137 to determine the positions of the auxiliary plungers of the pumps and consequently to determine the extent of movement of these plungers, thereby regulating the quantity of oil or oil and water discharged by each pump every time the plunger is actuated. '7

The construction and location of the pumps, as hereinhefore described are particularly adapted for comparatively small engines, that is engines of comparatively small horse power. a

In larger engines. it i preferable to locate each pump adjacent the point on each cyl-.: ihd'eratwhich the injection of oil or oil and water is made, and therefore instead of actuating the pump plungers directly, as is done by themechanism hcreinbefore depoints-ativhicb the injection is admitted. 0

These comprise contacting membcrs MS and 14+ adapted to be engaged by the contact 7 surfaces of the reciprocating plunger nemher and each pivotally connected to one and is suitably jonrnaled thereimand-the lever 146 is similarly connected to. a shaft 148. The opposite end of thelver '145 is pivotally connected to one end of a link 14 9;

. in connection with Figs. 17 and '18. but inasthe opposite end of which is connected to the endof one arm of a bell crank lever 151. This bell crank lever is mounted on a shaft 153 and the end of its other arm is pivotally connected to a socket 155.

Similarly. to operate the other pump-the opposite end of the lever 146 is connected to one end of a link 150, the opposite end of which is pivotally connected to the end of one ul'lll of a bell crank lcvcr 152 mounted on a shaft 154. the end of the other arm of which being pivotally connected to a socket 156.

The end of the pump plunger rod 157 fits within the socket 155 and the corresponding end of the pump plunger rod 158 fits within the socket, 156, the rod 157 beingadapted to actuate one or more pumps. and the rod 158 to actuate one or more other pumps, these being connected respectively to the auxiliary pump plungers 159'and 160.

The eccentrics 126. 135. Fig. 2%. are m vided Withstops 155' and 156' acting to de termine the length of the strokes of rods 157 and 158. in the same manner that the stop levers 120 and 120 determine the stroke of the auxiliary plungcrs 115.

Theform of'pump prcfcrabl employed is located adjacent the injection point. as shown in Fig. 25'. This comprises a body 161 fitted with a plunger 162, suction connections 163, and a discharge connection 164. the arrangement of the ports and suction and discharge connections being Somewhatdifferent to those shown and described much as the pump construction forms no part of my present invention, no further description of the same is deemed necessary.

Referring again to Figs. 1 and 2. the discharge of the pump 101 is connected by a pipe 165 to the intake connection 167 of the cylinder 13. and the discharge from the pumpQlOQYis connected by the pipe 166 to the intake connection 168 of the cylinder 14. each cylinder being provided with an ignition "chamber 169 at its upper end and a cap 170, the injection connection heing so placed as to direct the fuel into the ignition chamber and'so constructed as to prevent its return through the supply pipe. These members, however, form no part of the present invention. a

In the operation of the herelnbefore described apparatus, the governor is turned by the engine shaft when running through the key- 82, and while mounted to turn on the en ine'shaft the eccentric member-93 is turne with the shaft through its connection with thegovernor, as hereinbefore described, and as will be understood the relative position of the eccentric member 93 on the. shaft is dependent upon the speed at which the same turns, varying of course with the positions of the governor weights .plate.

83 which. due to ceni ritugal action. are ex tended further against the action of the springs 88 from the axis on the shaft as the speed of the engine increases.

The eccentricrecentric strap 68 is also turned with the governor by the pin 100. and it is connected with the plate 97 and the sleeve '95 extending from the governor. also as hcrcinbcforc described. This eccentric eccentric-strap is turned within the e'cccntric strap (3061 by which. as will be understood. a reciprocating motion is imparted to they plunger plate 55. the striking or contact surfaces of which are made in the arc of a circle. whose center is preferably the so center of the plate which coincides with the center of the engine shaft.

The cranks on the engine shaft are set at 180 apart and consequently in each revolution thereof. when moved in one direction 35 the reciprocating plunger platc strikes the auxiliary plunger of one pump and actu ates its main plunger to force the oil and water injection into one cylinder and when moved in the other direction the opposite contact surface of the reciprocating plun- K gcr strikes the anxiliarv plunger of the other pump to operate its main plunger and force the injection of oil and Water into the other engine cylinder.

Obviously, in the operation of the engine, thccenters of the eccentric member 93, in the eccentric eccentric strap 68, vary moving apart or comingtogether, depending upon the speed of the engine resulting, as will be understood, in the resultant variation in the length of the travel or stroke of the reciprocating plunger plate 55, which, as will be understood. correspondingly varies the stroke of the pump pistons with a corresponding variation in the amount or quantity of the fuel-and \vater injected into the cylinder.

is injected into thecylinders is dependent 116 upon the position of the lever 72 and the} rocker disk 44, which determlne the angu'- lar position of the reciprocating plunger It will further be understood that by shiftingthe lever 72 and the rocker disk 44 to the extreme position in one direction,

as shown in Fig; 2, for the purpose of clearness in illustration, the injection of the fuel supply may be made atspch a time as to obtain a pro-ignition resulting ln the reversalof the engine, which will continue to run in this direction when the lever 72 s shifted back to its normal operativepog tiongwhen the engine will continue to run. .130

in the reversed direction. Obviously, also, to again reverse the engine, the lever 72 and the l'orltcl' disk 44 may belshifttal to the other i-xlrcmc position to obtain another pro-igniliou, resulting again in the reversal of the engine.

As herrinbefore described, the lever 131 may .be'adjnsted to poisition to determine the position of the stop levers 120 and 121, which in turn control the positionsand return strokes of the [dangers of the pumps, and by the lever 131 and the parts intermediate of the same and the stop levers 120 and 121, as hereinbefore described, the pump plunger may be so placed as to bring the contact surface of the auxiliary pump plungers entirely out of the path of the contact surfaces of the reciprocating plunger plate 535. In other words, the stop levers 120 and 121 may be so adjusted by the lever 125i and the intermediate parts to vary the stroke of the pump plungers from zero to a maxi mum.

It will also be apparent that the levers 7+ and 131 may be actuated in conjunction with one another to operate the parts liereinbefore described in the stopping, reversal and other controlling of the engine, and also that the water su ply may be so regulated and controlled t at through the action of the governor suliicient Water may be injected with the oil or other liquid fuel charge to maintain a constant temperature. in the engine cylinders.
